Southern Baked Yellow Squash

3 pounds yellow summer squash, cut into 1-inch cubes

½ cup dry bread crumbs

½ cup chopped onion

2 eggs

¼ cup butter, melted

1 tablespoon white sugar

1 teaspoon salt

½ teaspoon black pepper

¼ cup butter, melted

¼ cup dry bread crumbs

Preheat an oven to 375 degrees F (190 degrees C). Grease a 2-quart baking dish.

Place the squash in a large saucepan, cover with water, and boil until soft, about 15 minutes. Drain the squash well, place in a large mixing bowl, and mash until slightly chunky. Stir in 1/2 cup of bread crumbs, onion, eggs, 1/4 cup of butter, sugar, salt, and pepper until thoroughly combined, and spread mixture into the prepared baking dish. Drizzle the top of the casserole with 1/4 cup melted butter, and sprinkle 1/4 cup bread crumbs over the butter.

Bake in the preheated oven until the casserole is cooked through and the top is golden brown, about 1 hour.
